Proof of stake will reduce nvidia sells

Nvidia, one of main productor of graphical cards, may suffer a reduction in sell in next months.

The cause maybe the trasformations of cryptocoin algo from Prof of work to Prof of stake.

With prof of work miners need powerfull graphics cards to mine and take the rewards of mining
With prof of stakes power does'nt matter, the only necessity is disk space and continuous internet connection.

Market already seems starting change direction.
